The cost composition of rapid deep drawing sheet metal prototype parts mainly includes the following aspects:
Mold design and processing: Deep drawing stamping parts require specific molds to form the parts, especially for prototype parts with very small quantities and extremely short delivery requirements or small batch production. The optimization design and rapid manufacturing capabilities of the molds (fast soft molds) greatly test the comprehensive strength of a prototype factory. Due to its difference from large-scale production, the cost of rapid soft molds is usually reflected more prominently in the price of small quantities of prototype parts.
Raw material procurement: Although the cost of raw materials itself accounts for a very small proportion of the total price of prototype parts with a small quantity, the procurement process for special and urgent raw material needs usually incurs high labor costs. In addition, there are significant differences in the prices and applicability of different materials. For example, the prices and deep tensile properties of different models of stainless steel vary significantly, so choosing the appropriate material requires reasonable cost control while meeting performance requirements.
Rapid soft mold testing process: For the processing of sheet metal deep drawing stamping prototype parts with short lead times and small quantities, the mold testing stage usually consumes a significant amount of manpower and material costs.
Design and processing of auxiliary fixtures: During the parts processing, surface treatment, and quality inspection stages, due to the special nature of the new product, it is usually necessary to design and manufacture special fixtures and auxiliary mechanisms to complete the parts processing, surface treatment, and inspection process.
Purchase of special testing tools and services: Similar to special fixtures, for new prototype parts, it occasionally involves the purchase and use of special testing tools, as well as the purchase of testing and inspection services from other third-party organizations.
In summary, due to the fact that the number of parts processed by rapid sheet metal deep drawing prototype models is usually small, after sharing the main costs mentioned above, the unit price of parts is usually relatively expensive.
